Explorer XXXVIII (RAE-A), launched from WTR July 4, was adjudged successful by NASA. Satellite had completed 30 days of suc­cessful three-axis gravity-gradient-stabilized operation in orbit as of Aug. 22. Experiment instrumentation and all spacecraft support sys­tems were operational and functioning satisfactorily. Recording of vari­ations in galactic emission, low-frequency solar bursts, and radio sig­nals from earth had been acquired. Some evidence had been found of enhanced noise bands at medium frequencies within magnetosphere, and strong noise enhancement had been observed in vicinity of South Atlantic anomaly. (NASA Proj Off)

Aerobee 150 sounding rocket launched by NASA from portable launcher at wSMR carried GSFC payload to 3.1-mi (5.05-km) altitude. Objectives were to flight-qualify production lot of VAM-20 variboosters, demon­strate Aerobee rail launch feasibility, determine exiting loads on rail launcher, establish procedures for rail launching, and verify boost-phase dispersion calculations. Booster web burning time, booster pres­sure, acceleration, velocity, and system impact were as predicted. (NASA Rpt SRL)

X-15 No. 1 was successfully flown by Maj. William J. Knight (USAF) to 254,100-ft altitude and 3,716 mph (mach 5.26) in test from Edwards AFB. Primary objectives were to conduct WTR experiment and check out horizon scanner, fixed alpha cone, and fluidic probe. (X-15 Proj Off)

Presidcnt Johnson selected Dr. Glenn T. Seaborg, AEC Chairman, to head U.S. delegation to 12th conference of International Atomic En­ergy Agency, which would open in Vienna Sept. 24. (UPI, NYT, 9/15/68, 34)
